To all whom it may concern:

' Be it known that we, MAX Rorron and ROBERT RoHDE, citizens of the German Re public, residing I This invention relates to roller-safety razor and our objects are to fit same with removable rollers, elastic bearing arms for said rollers and with lather wipers for single as well as for double-edged safety blades or razors.

Our objects are attained by mechanism such as will now be describedwith reference to the annexed drawingsgivenby way of example, in which I .Figure 1 is an end elevation, partly in section, of one form of construction; Fig. 2, a side view with part of the handle broken away; Fig. 3, a plan; Fig. 4, a plan with parts removed; Fi .'5, an end view with handle, rollers an razorv blade removed; Figs. '6, 7, 8 and 9 arean end view, side view, plan and longitudinal section respectively of a modified construction; Figs. 10 to 13 are an edge view, side view, plan and an end view of a corresponding detail of a further modified construction; .and. Fig. 14 is "a side view of another.modificati on.

In all the figures the same or SlII11l3I- parts are denoted bythe reference char Referring first to Figs. 1 to 5, 1 denotes the outer clamping plate and- 2' theinner clamping plate to which plates 2. screw-adjustment 3, 4 and guide pins 5 and 6 are fitted. The plate'2 carries elastic arms 9-, 10 79nd 8 are mounted close to the inner-side -of-which are the wipers 13 and 14, while a double-edged razor blade '15. is clamped between theplates 1 and 2 by an app-ropriate' adjustment of the screw-device 3 and 4. The plate 2 is fitted with a hollow handle 16, while the elastic'arms 9 to 12 and the lather-wipers 1'3, 14 are madein one piece.

11 and 12 in which 7 the safety rollers.

may through the slots 17 18.

However, the arms may be fixed by riveting 1' in any othermanner. The wipers- 13, 14 consist each of a ledge orrail turned upward to leave a small space for'the free play of the rollers 7 and 8. A slot 17 is made in the ledge 13 and a slot 18 in the ledge 14 to allow the lather removed in shaving to pass through such slot and become deposited 'on to the inner clamping plate. The guide pins 5 and 6 and the'pinscrew 3 1 are fixed to the outer clamping plate 1 in pdsitions to fit into holes provided in theplate 2. The roller 7 is smooth and roller 8 is corrugated, but both may be corrugated or smooth, or spirally grooved.

Fig. 4 illustrates the manner of removing the safety -rollers. In forcing the roller endwise ainstone of its elastic bearing arms it w1ll be powible to withdraw the trunnion of the roller at the other end, then remove the roller and allow the elastic arm 11- to straighten out.

The constructional form shown in Figs. 6 to 9 comprises the same parts denoted by the same numerals as above described, the wipers 13, 14 being shortened and the operative edges of same being turned di-. rect towards. the rollers, while the elastic bearing arms 9 to '12 are fast on the outer clamping plate 1.

The third constructional form shown in Figs. 10 to 13," comprises an outer clamping plate 1 with screw 3 and guide pins'5 and 6,=

adapted to coast with the inner plate '2 carryingthe arms 9 to 12, wipers blade is shown between the plates 1 and 2. The elastic 9 to ,12' are here bent in the form of hooks and are subsequently fixed to :or form the wipers13, 14 which in, other respects are similar to those shown in Figs. llto 5. The rollers are smooth, but

they ma have theforms shownin Figs. 1 to 9 and .t ey are withdrawable in the manner' illustrated in Fig. 4. The screw-connection corresponds with that shown in Figs. 1 .to 5, but other screw-connections be adopted The lather escapes The modification shown in 4 has a straight razor-blade 15, the screw-connection and other parts may have any of the previously described forms.

62; magma subsequently fixed to either the outer or th inner clamping plate.

The slot for the passage of lather may be a single slot, series of successive slots 19 interrupted by bridge pieces as shown in Fig. 15, or adouble slot wit-h open ends as shown in Fig. 16.

I claim: 1. In asafety roller razor'the combination of a soap lather wiper with rollers. the inner clamping plate being provided with four elastic bearing-arms which permit of the removal and reintegration of the guard rollers for cleaning purposes and at the same time form bearings for the same. so that between the curved or straight outer and inner clamping plates with guide pins fast in the outer clamping plate, the blade guided by the inner clamping plate, can be set by the screw-device of which the stud screw is fixed in tlfeouter clamping plate, while the adjusting nut forms the handle. 2. A safety razor "comprising an outer clamping plate, an inner clamping plate having resilient arms at its ends, and said inner plate being further provided at its The elastic bearing arms in any of the foregoing constructions maybe integral or opposite sides with inwardly bent wiper flanges and lather clearing slots in said flanges, connecting means for said plates to clamp a razor blade therebetween, and rollers detachably revolubly mounted between the ends ofsaid resilient arms and opposite which said wiper flanges bear.

3. A safety razor comprising an outer clamping plate, an inner clamplng plate having resilient arms at its ends, and said inner plate being further provided at its opposite sides with inwardly bent wiper flanges and lather clearing slots in said flanges, connecting means for said plates to clamp a. razor blade therebetween, and rollers detachably revolubly mounted between the ends of said resilient arms and opposite which said wiper flanges bear, said resilient arms forming the ends of said wiper flanges.

In testimony whereof we affix our signatures in presence of two witnesses.
